The withered neck of the archegone, which has assumed a deep reddish brown colour, may often be recognised for some time surmounting the apex of the calypter. The mature sporogone consists of a pedicel or ^/a^which is usually of considerable length, the lower portion or foot being enclosed within the vagine, but is short in Sphagnum and some other genera—arid the sporange or spore-capsule surmounted by the calypter, while the base of the seta is surrounded by the sheath-like vagine. The wall of the sporange is coniposed of several layers of cells, the outermost of which has a distinctly epidermal cha- racter, and is sometimes perforated by stomates with imperfect Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Bennett, Alfred W.
